Fantastic way to try something before you order it!

Remarkable sizing system for the Oura fitness rings.

Thank you very much for having this kit in stock. I was told by a sales associate that you don't have rings in stock so this was helpful. I also was told the sizing guide in the display is inaccurate, so doubly glad you had the sizing kit! I eventually purchased a ring from Best Buy!

Great product to size the oura ring. It worked out perfectly.

The product was helpful in deciding what size to get. I also used the sizer and pretended it was the real thing to see if id get uncomfortable wearing it since I dont wear jewelry often. I also wore it to see how well id keep track of the real thing once I get it.

Oura ring sizing kit was necessary to decide on the appropriate ring size as this size varies from normal sizing.

Great way to get the right fit before purchasing the ring.

The kit pays for itself with the girftcard. Gives you a chance to see how it will feel.

perfect fit before buying the OURA ring - good invest

Very good and accurate ring guide was very useful in picking the oura ring, since they tell you to wear it on your index finger, it a much different size than the ring finger for us.

Highly will recommend getting this before purchasing the real deal that way it saves you the hassle of returning it and you will have the felling on how it feels on your finger

I’m glad I got the kit because I was almost certainly going to get an Oura ring until I tried one of these on. I’m relieved I didn’t spend $500 on a bulky ring that I would’ve hated wearing.

Ring sizer is easy to use and worked for me. Definitely worth testing out a prototype ring before making a purchase

If you are planing on getting the Oura use the zing kit and try it for a few days o see what works before buying the actual product

I bought this to get the sizing for the Oura ring. Was nice to get a $10 Best Buy reward for this item and ended up using it towards a ring. I wore the sizer for several days to make sure it fit without ever getting too tight or too loose.

Helped with finding the perfect size for the perfect ring for my sons

Helped me to determine if I wanted the gen 3 or gen 4 and what finger id want to wear it on and what size to get!

A must before buying an Oura ring but it’s not exactly the same as an Oura (I had to exchange my Oura ring for a size smaller when the ring I bought would fall off my finger when my hands were wet (same size from the sizing kit had no issues).

They are pieces of plastic that replicate what each ring size would feel like. I found it very helpful because no variation was comfortable for me and I learned the Oura is not for me.

If your worried the device won't fit they send a whole box of plastic rings to try out. For plastic rings pretty good quality.
